This sparked a small discussion between my husband and I about how we like to be thanked - he would find someone reading him a "gratitude letter" out loud a horrible experience, while I thought it was sweet. There was also one fellow on the program who tried to write Thank You notes to Everyone, Every Day, who did Anything nice for him. My thought - how do you have time to be out and about where people can be nice to you!
When I first started my job at the church, the minister was engaged in an effort to write three Thank You cards a week and send them to folks in the church. He challenged me to try it also as a practice, and I have been. Sometimes it's not exactly three, but on Mondays I reflect over the week previous and write little notes to folks just telling them Thank You for what they did that week.
I love this as a practice. It makes me reflect and focus on what other people did, and honestly sometimes it's too easy to only see what you contribute, while in reality there are so many folks doing things both big and small that deserve notice. I also find that I'm happier in my job, and have an easier time asking for help and approaching people as possible volunteers.
Even if you don't have a job like mine that involves volunteer management, there are benefits to a gratitude practice of some kind. How can you say 'Thank You' more often (and mean it)?
